2 General Information
2.1 About this Guide
This guide is comprised of the on-screen Help instructions available on the instrument itself, plus some essential extra information, e.g. Safety. The on-screen Help is split into Topics associated with each sub-menu of the five top-level menu groups; each Topic explains the functions accessible via that sub-menu, see section 3.8.2 for details. In the on-screen Help the
Topic headings and function headings, which are context sensitive to the current menu selection, are highlighted in green text for easy reference; in this guide the same headings are shown shaded, e.g. Specifications and Capabilities, Frequency, etc.
The function headings shaded in this way are mostly the names of the menu and function softkeys as they appear on the screen. Note, however, that the keys of pop-up menus are described within the associated function and do not have their own shaded heading; instead they are identified in the text using ‘ ‘, e.g. ‘Set by Tab/Jog’. The hard keys are also identified in this guide in the same way, e.g. ‘Navigate Screen’, ‘View’.
In this guide, as on the Help screen, > between key names indicates the sequence of keys needed to select the function described.
2.2 Specifications and Capabilities
The PSA6005 and PSA3605 are portable spectrum analyzers incorporating a high resolution colour TFT touch screen. They are sufficiently small and lightweight to be operated as a true handheld instruments and have a battery life of more than three hours from each charge.

2.7 Battery and AC Line Operation
The instruments operate from an internal Li-ion polymer rechargeable battery which can provide more than 3 hours of continuous operation (screen brightness dependent).
The battery is charged from the supplied 5V/2A charger which can recharge a fully discharged battery in under 3 hours.
Only use the charger supplied to recharge the instrument.
The battery condition is indicated on the display; when it displays a single segment and changes colour, expected battery life has fallen below 30 minutes.
The instrument can be operated continuously from this external charger for bench-top operation. When the battery is being charged, the LED next to the charging socket flashes.
When charging is complete, flashing ceases but the LED remains on while the charger is connected.
2.8 Bench Stand and Screen Protector
The instrument is intended for both portable and bench-top applications.
It is supplied with the tilt stand folded away at the back of the instrument. This can be hinged outwards to set an angle of about 40 degrees.
To protect the screen when in transit, the stand can be detached from the base and re-attached on the top to act as a screen protector.
The stand is detached by flexing the sides until the locating lugs disengage from the body.
For outdoors use, the screen protector can be hinged upwards to form a sun shield which improves the screen visibility in sun light.
When not required, it can be detached and stowed away on the back of the instrument.
2.9 Touch-screen and Hard Keys
The normal mode of operation of the instrument is by using the touch-screen keys at the bottom of the display supplemented, when required, by the hard keys below the display.
The touch screen keys are normally operated by pressing firmly with the finger or thumb, or gently with a finger nail. Alternatively they can be operated using the supplied stylus which clips into the base of the instrument.
It is also possible to use the instrument without touching the screen at all, by using the five
‘navigator’ hard keys to operate each of the touch screen functions.
2.9.1 Using hard keys to navigate the touch-screen
Pressing the circular button marked ‘Navigate Screen’ changes the function of the five
Navigator keys from controlling the Markers to controlling the position of the on-screen key highlight. The highlight position is shown by a change in the key colour to purple. Pressing the centre button operates the selected key.

3 Quick Start Guide
It is recommended that all users, including those fully familiar with RF spectrum analyzers, take a little time to read through this manual before using the instrument.
However, for users who wish to get started with hands-on operation as quickly as possible, the following may prove useful.
1. Press and hold the Power key until a short beep is heard. Wait a few seconds and then check the battery condition indicator on the display. If it shows less than ¼ full the instrument should be connected to its charger.
2. Connect the signal to be measured to the N-type connector at the top of the instrument. The maximum allowable signal without damage is +25dBm (+132dBuV or 4V rms). The maximum measurable signal is +20dBm (+ 127dBuV or 2.23mV rms). If there is a possibility of the signal exceeding these levels, add suitable in-line attenuation.
3. Ensure that the Navigator keys are set to Control Markers (key illuminated green). If not press the round key marked Control Markers. This also selects Touch Screen key control.
4. Press the hard key marked Presets (Auto-Set). Select Auto Set and press Execute.
The instrument will perform a full span sweep (10MHz to 3590/5990MHz) at maximum reference level (+20dBm) and find the highest level within the sweep. It will then perform a number of further sweeps at narrower spans and, where appropriate, lower reference levels.
During this time a red background message of Status: SCANNING with be displayed. When finished the message will become Status: COMPLETE.
When Auto Set has completed, the analyzer should be set with a fairly narrow span (typically
10MHz) centred on the signal with the M1 marker at the centre frequency and in Peak-find mode (indicated by an upwards arrow prior to the M1 readout). RBW will be set to Auto and
VBW to Track.
5. Press Exit to return to the main menu.
The M2 marker can be turned on from the hard key marked Control Markers. Markers are moved using the Navigator hard keys – Left/Right moves the markers, Up sets peak-find mode where the selected marker jumps to peaks within the trace, Down sets scroll mode where the marker moves pixel by pixel across the screen. The marker currently under control is selected by the centre key (M1/M2) and indicated by an arrow before the marker readout.
From the main menu adjustments can be made to centre frequency and span (or start and stop), sweep mode, detector type, RBW and VBW, reference level, displayed traces and markers.
The menu system is hierarchical with each top-line key selecting a set of five second-line sub-menu keys. Each of these provides access to a set of keys on the bottom line that perform the actual functions.
Context sensitive help for each sub-menu group can be accessed by pressing the hard key marked “Status (Help)” followed, if not already selected, by Context Help. This provides sufficient information to understand the principles of operation.

4 Menu System
4.1 Control via the Menu System
The default menu system for the instrument consists of three rows of five keys. The upper row represents the top level of the menu system and defines five menu groups as follows:
Freq/Span controls the frequency range of the spectrum analyzer, as well as Zero Span mode.
Sweep/BW controls the sweep and sets the RBW.
Level/Limits controls the input attenuator, plus the scaling of the amplitude display. Limits is only available with option U02 fitted.
Traces/Markers controls the traces that appear on the screen (including store/recall) and the markers that are used for measurement.
Setup/Functions controls specific measurement functions and instrument setup store and recall. Automatic Measurements and Logging are also controlled with option U02 fitted.
Each group has up to five sub-groups which appear on the middle row of keys. The currently selected group and sub-group are shown by the relevant keys being dark blue.
The bottom row of keys represent the functions that can be performed for each of the many sub-groups. These keys may perform an immediate action, or bring up a pop-up menu, or create a dialogue box for user entry. Specific functions such as frequency entry and filing system operations replace the normal menu keys with a new set of keys relevant to the current function.
4.2 Hard Keys
Run/Stop (Manual) controls the sweep. It duplicates the function of the touch screen key directly below the graticule.
Exit (Cancel) terminates any pop-up menu or dialogue box.
Status (Help) brings up complete listings of the instrument status, and gives access to the
System Utilities and on-screen Help.
View (Live > View) copies an instance of the Live trace to the View trace. This duplicates the action of the soft key Traces/Markers > Traces/Stores > View.
Presets (Auto Set) activates the Presets menu: Standard Preset, User Preset and Auto Set.
Navigator Keys the five hard keys that make up the Navigator have two alternative modes of operation which are selected by the small illuminated keys on either side. The modes are:
Control Markers (default), and Navigate Screen (see section 2.9.1).
Whenever the navigator mode is changed, an information box appears explaining the current action of the navigator keys. This can be turned off if preferred from

Repeat Single
Repeat causes the sweep to run continuously unless it is stopped with the Sweep Control key. Single causes single sweeps to be performed in response to the Sweep Control key.
When option U02 is installed Sweep Triggering is available. The trigger event stops the sweep when in Repeat mode, and starts the sweep when in Single mode.
Sweep Trigger creates a pop-up menu from which the trigger source can be selected. Note that Limits triggering is only available in Repeat mode.
Single ReArm Only applies to Single sweep mode. When set to Auto, the trigger is re-armed to accept new trigger events at the end of the sweep. When set to Manual, the Sweep Control key must be pressed before another sweep can be triggered.
4.4.4 Sweep Control Key
Running

This key is placed directly below the graticule on the right hand side of the screen.
Its action is duplicated by the hard key marked ‘Run/Stop’.
The function of the key is to start and stop the sweep when in Repeat mode, and to initiate the sweep when in Single mode. The colour and marking of the key changes to show the current status of the sweep.
4.4.5 Sweep Progress Bar
When the sweep time is greater than about 1 second, the sweep is drawn progressively across the screen. In this mode a yellow sweep progress line is shown at the bottom of the graticule.
4.4.6 Sweep/BW > Sweep Mode
Sweep
This menu controls the sweep methods used to suppress signal images and other
Mode spurii. Combined analog and digital techniques are used to achieve image suppression, and the user can choose between methods that may offer improved performance for specific situations.
Normal
(Auto)
Normal (Auto) is the default mode in which images are suppressed in real time. An alignment procedure is used which can briefly interrupt the sweep. This can be avoided using settings within Advanced Options.
Manual
Align
Reveal
Images
Manual Align is available if Normal (Manual) has been selected in Advanced
Options.
Reveal Images disables image rejection for one sweep or 1.5 seconds, whichever is the longer. During this period any signal images close to or within the noise are revealed at full level.
Advanced
Options
Advanced Options opens a further menu from which alternative image rejection sweep modes can be selected. This menu has its own context-sensitive Help.
Normal Sweep Mode rejects the images of a signal in real time as the sweep progresses. To ensure sufficient rejection to bring the image down to the noise floor, an alignment procedure is run when the instrument is first switched on and occasionally thereafter as temperature and other parameters change over time.
Normal (Auto) is the default mode in which the sweep pauses briefly when alignment is needed.
- 12 -
Threshold - the need for alignment can be controlled by setting the amount by which a possible image can rise above the noise floor. This can be set between 0dB and 12dB, higher values reduce the need for alignment.
Normal (Manual) can be used if occasional interruption of the sweep is unacceptable. When the instrument calculates that alignment is needed (as defined by the Threshold setting) a message is displayed and the Manual Align key or Status hard key can be used to initiate the alignment.
D.C. Sweep Modes DC (data comparison) sweep modes provide a different balance between sweep speed, image rejection and noise floor from the normal modes. They have the potential to provide total image rejection combined with reduced general spurii. No alignment is required.
Disadvantages include slower sweep for narrow spans at narrow RBWs, and vulnerability to image rejection loss for specific signal spacings and for rapidly changing signal levels.
D.C. Mode 1 provides perfect image rejection for constant level signals provided that there are no signals spaced at 40MHz +/-(2xRBW) apart. Sweep speed reduction for narrow spans is moderate.
D.C. Mode 2 retains rejection unless signals exist simultaneously at both 32MHz +/-(2xRBW) and 40MHz +/-(2xRBW) apart. Sweep speed reduction is slightly greater than for Mode 1.
Signal images and image rejection ratio are explained in the full instruction manual.

Graticule dBm
Graticule
Enables the level to be shown in either dBm or in dB microvolts. It also enables the brightness of the graticule to be controlled. dBuV dBm selects level measurement in dBm (decibels relative to 1mW into 50
Ohms). dBuV selects level measurement in dB micro volts.
Note that the measurement unit applies to both the graticule values and to the marker level readout.
Graticule creates a pop-up menu enabling the graticule to be dimmed, set to levels only (horizontal lines only) or turned off completely.
4.5.2 Level/Limits > Reference Level

4.5.3 Maximum Signal Levels
Signals that exceed the reference level may result in measurement errors even where the excess signal is outside of the current span.
The maximum allowable input is +25dBm or +132dBuV of RF power (approximately 4 volts
RMS), or 50V DC. Applying a signal above these levels could damage the unit and such damage would not be covered by the product warranty.
Signals that would cause the trace to rise above the reference level are indicated by a red arrow at the top of the graticule. In addition, overload of the ADC can occur which is indicated by a warning message below the graticule.
4.5.4 Level/Limits > Scale/Shift
Scale/

Clear
Set
Clear All turns off any offsets and any compensation tables that were set to on.
Set opens a new control menu with keys as described below.
All
75 Ohm adds a fixed offset to compensate for signals coming from a 75 Ohm source.
Fixed Offset enables an offset between -50.0 and +50.0dB to be added to the reference level.
Take care not to overload the input.
Comp. Table enables a file to be loaded that compensates for frequency dependent external devices such as antennae.
On and Off turns the currently selected offset or compensation on or off.
Set Offset opens a numeric or Tab/Jog screen from which the fixed offset can be set.
Select Table opens a file recall screen for compensation tables created in PSA-Manager.
4.5.6 Level/Limits > Limits
Limits
Limit lines, limit patterns and limits comparison functions are only available when Option
U02 is installed. Limits can be simple straight lines or complex patterns of level against frequency. Up to two limits can be used together - Limit 1 is red, Limit 2 is blue. A limits comparator compares the signal with the limits and can create conditional actions.
Set
Set Limits opens a new control menu which enables one or two limits to be set using keys
Limits as follows: Limit1/Limit2 selects which limit is to be set-up or turned on or off.
Set Line opens a numeric or Tab/Jog screen from which a fixed level can be set in dBm or dBuV. Select Pattern opens a file recall screen for limit pattern tables created in PSA-Manager.
Limit On/Off sets the currently selected limit (1 or 2) to be turned on or off.
Limit
Condition
Limit Condition opens pop-up menu which defines how the comparison between the signal and the limits will be made. Where two markers are displayed, comparison only takes place between the markers. If not, the whole trace is compared.
Above/Below intended for single limits, action will be created if the signal goes above/below the limit.
Inside/Outside intended for dual limits, action will be created if the signal falls between (inside) the two limits or goes outside of either.
- 14 -
Limit
Action
Limit Action opens pop-up menu which defines the action that will take place when the limit condition is met. This can be an audible beep, a pulse from the trigger socket, or both.
Further actions of Sweep Triggering or Data Logging can be created from the respective function menus. The action is created at the end of the sweep.
Limit
Offset
Limit Offset opens a new control screen from which a limit can be offset from its initial values. This is particularly useful for limit patterns which would otherwise have to be recreated.
Limit
Fix/Unfix
Limit Fix/Unfix fixes the limit pattern on the screen so that it will not change when the centre frequency is changed. A message is displayed within the graticule area. This allows a pattern to be used for alternative\n frequency points. Unfix recalculates the pattern for the current frequency range and level..
Channel Markers are a special case of a limit pattern file which create only vertical lines at frequency points defined in the file. Channel marker files are created within PSA Manager and have files names starting with a $ symbol.
4.6 Traces/Markers
4.6.1 Traces/Markers > Traces Control
Traces
Control
View
Swap

Single Trace selects the default mode in which the processed trace only (Peak
Hold or Average) is displayed.
Dual Trace displays the normal un-processed trace in green with the last complete processed trace (Peak Hold or Average) behind it in yellow. Note that the yellow trace is updated only at the end of the sweep and can therefore lag the green trace.
Dual
Trace
Swap Traces causes the processed trace (Peak Hold or Average) to be displayed in green and updated in real time. The yellow trace becomes the un-processed trace which is updated at the end of the sweep and can therefore lag the green trace.
Note that Markers and Store Trace functions operate only on the green trace.
Average

More 2 of 2 returns to the other set of function keys.
4.6.3 Traces/Markers > Traces Stores
Trace
Stores
Controls the storing and recalling of the reference traces and of screen images. Trace files contain the amplitudes value of the trace along with the related frequency range and RBW.
The Live or View traces can be stored. Screen Image files are ‘pictures’ of the whole screen (excluding the key area).
Store
Store creates a new control screen with keys as follows:
The top line of keys selects what will be stored, the Live Trace, View Trace or Screen
Image.
Quick Save saves the file under a default name that auto-increments from 001 to 999. The trace update re-starts once the save is completed.
Save As pauses the trace update and opens a second control screen that enables a custom name to chosen. The keys are as follows:
Change Name brings up an alpha-numeric keypad from which a new file name of up to eight characters can be entered.
Change Default enables the default file name used for Quick Save to be changed. Up to five characters can be used.
File Utilities brings up a file window from which all existing files can be seen, and allows them be deleted or renamed.
Recall

5 Maintenance | Updates | Further Information
5.1 Recalibration & Repair
To ensure that the accuracy of the instrument remains within specification, the calibration should be checked (and if necessary adjusted) annually. Aim-TTi or their agents overseas will provide a calibration service for any PSA3605/6005 and will repair any PSA developing a fault.
Where owners wish to undertake their own recalibration, this should only be done by skilled personnel in conjunction with the Service Guide which may be obtained directly from Aim-TTi or their agents overseas. Recalibration requires the use of a precision signal generator as specified in the Service Guide.
5.2 Cleaning
If the unit requires cleaning, use a cloth that is only lightly dampened with water or a mild detergent. Take particular care in cleaning the touch screen area.
5.3 Updating the Firmware
Updates to the instrument firmware may be made from time to time and are available to download at www.aimtti.com/go/psa. The latest version of the full instruction manual in PDF form can also be downloaded.
The method of updating requires the use of a USB Flash drive. Full information on how to perform the update will be provided with the firmware file.
5.4 Battery Replacement
The instrument is fitted with a rechargeable Lithium ion polymer battery which should only be recharged using the charger supplied.
The battery requires no maintenance but capacity will reduce over time and it may eventually require replacement. The battery is a custom design and replacements are only available from
Aim-TTi or from our authorised distributors or agents.
Refer to the Service Guide for detailed information on battery replacement and disposal.
5.5 Further Information
More detailed information on the use of the PSA6005 and PSA3605 is contained in the Full
Instruction Manual (English language only) which is supplied both as a printed booklet and in
PDF format on the support CD.
